Abstract
A data processing system backs up snapshots of storage objects to cloud storage by identifying to a cloud gateway a set of snapshots to be archived, and making the set available to the cloud gateway. Upon request by the cloud gateway, snapshot metadata is provided that includes offsets and lengths of data extents of the set of snapshots. On further request of the cloud gateway using the metadata, the data extents of the set of snapshots are provided to the cloud gateway, which uses the extents to create corresponding objects and stores the objects in the cloud storage, each object including the data extents and the snapshot metadata for a respective snapshot. Backup and restore are initiated by the gateway or by the data storage system in different embodiments.
